Find LCM of 380,702,627,974,805 with Prime Factorization
2 | 380, 702, 627, 974, 805 |
3 | 190, 351, 627, 487, 805 |
5 | 190, 117, 209, 487, 805 |
19 | 38, 117, 209, 487, 161 |
2, 117, 11, 487, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 2 x 117 x 11 x 487 x 161 = 115037182260
Therefore, the lowest common multiple of 380,702,627,974,805 is 115037182260.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
380 x 702 x 627 x 974 x 805 = 131142387776400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
627 : 1, 3, 11, 19, 33, 57, 209, 627
974 : 1, 2, 487, 974
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,702,627,974,805, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
702:2x 3x 3x 3x 13
627:3x 11x 19
974:2x 487
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 19 = 1140
Therefore, the value for common factors is 1140.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 131142387776400/(1x1140)
LCM = 131142387776400/1140
LCM = 115037182260
Thus, we can understand that the LCM of 380,702,627,974,805 is 115037182260.
